<div class="textblock"><p>Starting from v2.5.0, we have renamed Cpp-Taskflow to <em>Taskflow</em> to broaden its impact and support. Taskflow will explore multiple scopes of applications and language bindings, rather than just C++. This also made Taskflow naming more succinct and concise.</p>
<p>Taskflow 2.5.0 is the 7th release in the 2.x line! This release includes several new changes such as CPU-GPU tasking, web-based profiler, documentation, and unit tests.</p>
<h1><a class="anchor" id="release-2-5-0_download"></a>
